Application filed July 7, 1919. Serial o.'309,065.

To all whom it may concern:

Be it known that we, ARTHUR L. UPTON and SAMUEL N. IMMER, citizens of the United States, both residing at Houston, in the county of Harris and State of Texas, have invented new} {and useful Improvements in Burners, of which the following is a specification.

The object of the invention is to provide a simple, relatively inexpensive and efiicient burner for oil, wherein the parts are readily accessible for cleaning and repair and whereby there is assured an economical consumption of fuel with a maximum production of heat, and to this end the invention consists in the construction, combination and arrangement of parts hereinafter fully described, it being understood that changes in form, proportion and details may be resorted to within the scope of the appended claims, without departing, from the principles involved.

In the drawings:

Figure l is a sectional view of the complete burner,

Fig. 2 is a horizontal sectional view on the plane indicated by line 2-2 of Fig. 1,

Fig. 3 is a detail View showing a form of extended burner which may be used to fire a boiler at the rear end thereof to remove any tendency to the burning out 7 thereof.

The apparatus consists essentially of a the wall of the cylinder is secured by threading or otherwise, said head having openings 13 and 1 1 formed therein, preferably of respectively large and relatively small diameters, of which the former is fitted with a removable plug 15 having a nipple 16 for connection with a. fuel supply pipe 17 while in the latter or smaller of said openings is fit ted the burner pipe 18 which may be extended to either the front of the boiler as indicated in Fig. 1 (the boiler however not being shown) or as indicated at 18 to the rear of the boiler as indicatedv in Fig. 3, said burner pipe being fitted at its end remote from the I cylinder with a plug 19 and having a burner slot or outlet 20. r

The oil is supplied by the main or oil line 21 with which communicates the feed pipe 17 extending through the nipple provided on the above described plug 15, said feed pipe being provided with a controlling valve 22 and also including a coupling or union 23 by which it may be'disconnected from the main or oil line for cleaning purposes, repair and so forth.

F tted also in the openings 13 in the casting forming the head 12 is the cylindrical wall 21 of a retort designed to receive the oil from the supply pipe 17 and pro- ;steam feed pipe 30, which is in communication with a steam line or main 81 and is provided with a controlling valve 32 and an intermediate union or coupling 33 having a function similarto the coupling or union 28, namely to permit of the disconnection of the burner for the purpose of cleansing or repalring the same.

Communicating with an intermediate portion of the steam feed pipe 30 is a blowout pipe 34 which extends to and is capped into the fuel supply or feed pipe 17, valves 35 and 36 being provided therein to control the passage therethrough and an intermediate coupling or union 37 being employed for the purpose of disconnection when it is desired to detach the burner for the purposes hereinabove indicated. This blow-out pipe is intended to be used only for the purpose of cleaning the burner without detaching it from the steam and fuel supply main, the valves 35 and 36 normally being kept closed but when it is desired to remove sediment or other deposits from the interior of the retort and the fuel discharge pipe 27 the oil supply valve 22 may be closed and the valves 35 and 36 opened, so as to permit of the discharge ofsteam upwardly through the retort and thence downwardly and to the outlet 28' of said fuel discharge pipe 27.

It will be noted that the retort 24 into which the fuel oil is introduced from the feed pipe 17 is entirely inclosed'in the cylinder 10 which constitutes a steam chamber in which there is a continual circulation of steam introduced through the feed pipe 30, with the result that the fuel oil is partly or wholly vaporized before it escapes through the discharge pipe 27 to the outlet 28 where the mixture with the steam passing down through the passage 14 to provide the mixture to be burned'at the outlet 20.

It will be seen that the several parts of the apparatus are of independently simple construction and are connected in such a way as to be readily detached so that every part of the interior of the burner can be reached for cleansing purposes and the replacement of any part which may in use become in jured, may be accomplished readily and at small expense, while the relation between the parts are such as to insure an economical consumption of the fuel for the amount of heat generated thereby.

What I claim is 1. A burner having a steam circulating chamber, consisting of a cylindrical wall, having a head at one end thereof provided with openings, a plug fitted in one of said openings and provided with a fuel inlet, a burner pipe having communication with the other of said openings in the head, a retort cylinder also fitted in the first named opening of the head and provided at the opposite end with a plug having an outlet opening, a fuel discharge pipe in communication with the last named opening and eX- tending to and into said burner pipe, and a steam supply pipe in communication with the opposite end of the cylindrical casing from the said head. v

2. An oil burner having a cylindrical casing provided at one end with a steam inlet and at the other end with a head provided with openings in one of which is fitted a removable plug having an oil inlet, a burner pipe in communication with the other opening of said head, a retort having a cylindrical wall engaged in the first named opening of the head and provided at the opposite end with a fuel outlet, and a fuel pipe in communication with said fuel outlet and extending through the said casing and into the burner tube.

3. An oil burner having a cylindrical casing provided at one end with a domed head having a steam inlet opening, a head detachably fitted in the opposite end of the casing and provided with openings in one of which is removably fitted a plug having an oil inlet opening, a burner tube connected with a second named opening of said head, a retort mounted upon said head in communication with the oil inlet opening, and a fuel discharge tube in communication with the interior of said retort and extending through the casing and into the burner pipe.

4. The combination with steam and oil supply mains of a burner having a cylindrical casing provided at one end with a removable head, and an oil retort and burner tube respectively carried by said head, steam and oil feed pipes respectively extending from steam and oil mains and communicating respectively with the interiors of said casing and retort, said feed pipes being provided with couplings or unions, and a fuel pipe extending from and in communication with said retort and terminating within said burner pipe.

5. An oil burner having a cylindrical casing, a retort inclosed in said casing, steam and oil feed pipes respectively in communication With the casing and the retort, a burner tube in communication with the interior of the casing, and a fuel discharge pipe in communication with the interior of the retort and extending through said casing and into the burner pipe.

6. A burner having a steam chamber and an inclosed fuel retort, steam and fuel feed pi es in communication respectively with said steam chamber and retort, a burner tube in communication with the interior of the steam chamber, a fuel pipe in communication with the retort and extending through the steam chamber and into the burner pipe, and a blow-out pipe connecting the steam feed pipe with the oil feed pipe and provided with controlling valves, said steam and oil feed pipes also having cut off valves to interrupt communication between the same and said steam chamber and retort.

7. A burner for use in connection with steam and oil supply mains, having a steam chamber and a contained fuel retort, valved steam and fuel feed pipes in communication respectively with said steam chamber and retort, a valved blow-out pipe connecting the steam feed pipe with the fuel feed pipe, a burner pipe in communication with the interior of the steam chamber, and a fuel discharge pipe communicating with the retort and extending through the steam chamber and into the burner pipes, said steamand fuel feed pipes and the blow-out pipes being provided with intermediate unionsor couplings.

In testimony whereof we affix our signatures.
